Hello Michelle,
Safety edges are designed to only move away from an obstruction, if the downward safety has activated that would be why the lift is moving upward only. As the manufacturer we recommend that you get a qualifed stairlift engineer out to attend to the lift if tapping the edges and underpan of teh footplate does not recifty the problem.
It is vital that wiring for safety features, for example, is correct which is why you need an engineer who is familar with the product.
